A head sculpt can make or break a figure. Some of the nicest overall Transformers figures I have are occasionally let down by a weak head sculpt that is either too vague in its features, unrepresentative of the character it is supposed to be or just plain unpleasant. On the other hand, certain figures of an average nature can be elevated by a superb head sculpt which scores highly on the aforementioned criteria and exudes charm and character. This week I asked a few of my esteemed Transformers collecting peers to contribute their favourite official Transformers head sculpt across any era or sub-line, and explain why they chose it above the rest.
